That's the problem.  If you wrote

myTranspose =    \transpose c' c { }

then the transposition from c' to c would have referred to the curly
braces (and nothing else: myTranspose is just a single music
expression).  Written like you did it, it refers to staffOneName.

You probably need to write something like

myTranspose = #(define-music-function (parser location music) (ly:music?)
               #{ \transpose c' c $music #})

in order to have myTranspose take an argument.
